There are two species of squirrels that cause the most problems in our area :Eastern gray squirrels and Flying squirrels. If you hear animals in the attic, soffit or gutters during daylight hours, chances are that you may have Gray squirrels. If you are hearing the noises of a nocturnal critter, then you may have Flying squirrels. Both species of squirrels live in our area and love to make attics, walls and chimneys their homes.


How, When and Why They Enter Your Home

Squirrels have adapted well to urban and suburban environments. They frequently use homes and other buildings as nesting and breeding sites. They instinctively seek out safe den sites to bear and raise their young during the fall and spring.

Squirrels gain access to attics in several ways, usually by chewing the attic at the construction gap, roof vents, gable vents and other areas. They often find a small opening and chew a bigger hole to gain access to the building’s interior.

Squirrels bring nesting materials into the home or use items in the home for nesting material (insulation, stored belongings, etc.). Squirrels can gain entry to a home fairly quietly and may not make much noise while inside until they feel comfortable with their surroundings. Once these animals become more comfortable, they make quite a bit of noise scurrying around and storing food.

Juvenile gray squirrels can fall down a wall, get stuck and die.. However, flying squirrels may travel up and down walls to find a suitable nesting site without getting stuck.

Squirrels may live in your attic year-round, but they are especially active during the fall through the spring when the weather is cooler and they’re raising their babies. Your attic is an excellent place to raise them, as it provides protection from predators and the elements. If squirrels are present during this time of year, the adult females need to be checked to determine if they are nursing. If they are, the offspring should also be located.

Damage They Cause



Squirrels are members of the rodent family. Like all rodents, they must chew to keep their teeth sharp. Squirrels damage shingles, soffits and fascia boards by chewing them and enabling water to enter your home. If left uncorrected, this situation can cause a serious problem over the next several years, as water flows down the exterior walls, causing wood to rot. Worst of all, squirrels love to chew electrical wires and wire insulation until only bare copper is left. If the damage goes unnoticed, it can be a potential fire hazard.


When squirrels are occupying your home, they will use it as a latrine, leaving behind a lot of droppings and urine. These unwanted gifts not only smell bad, but they also pose a potential health risk. The smell can even attract new squirrels for years to come, as it can linger.


After squirrels have resided in the attic for any period of time, insulation damage is common. Loose-fill insulation will become matted and compressed, allowing heated air to escape into the attic in the winter and hot air to enter the home during the summer. Insulation replacement should not be completed until all the squirrels have been removed.
